TYPEWRITING MACHINE.

' Application filed December 12, 1925. Serial No. 74,958.

This invention relates to a device for facilitating the manipulation of work-sheets in typewriting machines of the Well-known Underwood fan-fold type.

In said fan-fold machines, a multiple ply web is usually drawn up from a supply at the rear of, the machine, the plies-bein interleaved with carbons, forming a pact which is inserted around the platen to be typed upon; the platen being elevated at intervals to reposition the carbons to a fresh portion of the web.

Sometimes it is desired to insert a cut form in registration with the first form of the web, because, in some cases, it is necessary to use one form to send to a customer, in which case a good grade of paper is used, and the balance of the-forms are used for interdepartmental work, which, of course,

does not require as good a grade of paper. According to the method of using this kind of a machine, the web is first fed up to a positioning gage, and then the platen is elevated, while the leading edge of the web is 'heldwith one hand against the gage, the out form being inserted between the platen and the feed-rolls, in a preliminary registering'position with the first form of the.

web. The platen is then lowered to its normal position and is rotated rearwardly, so as to bring the leading edge of the out form and of the web together, the two being reinserted under a knife in front of the platen, and both being, positioned for the first. line of typing. It will be understood that in order to manifoldthe first ply of the web, a carbon must interleave said ply and the out form, and, to this end, itis proposed to use an extra carbon underlying the first ply of the web.

After completely typin the'platen is rotated to fee the web against a cutting-off gage, and by so doing, the out form is ejected, the platen being again elevated'to strip the carbons previously'to tearing oiI the printed form of the web;

One of the features of this invention relates to a gage'for positioning the out form. Said gage has a turned-up edge for sitioning the leading edge of the cut orm,

' and a side gage forpositioning said ,form 1 laterally. Means are also provided for holding the out form when the laten is lowered toits normal position. Said means may be .the first form in the form of a clip forming an integral part ofthe upturned edge, which positions the out form in a line-space direction.

Another feature of this invention relates to a gage for positioning the web in registering position with the out form. Said gage is adjustably mounted on the front table and is provided with an upturned side edge for laterally positioning the'web and to prevent its accidental displacement during the platen elevating operation.

Other features and advantages will hereinafter appear. v

In the accompanying drawings,

Figure 1 is a cross-sectional view, in elevation, through the center of an Underwood fan-fold typewriting machine, and shows the invention applied thereto.

Figure 2 is an operating side View, showing the platen in its elevated position, and shows also the out form bein inserted between the platen and the fee -rolls.

Figure 3 is an operating View, showing the platen in its normal position, the knife being lowered to engage the leading edges of the web and the out form.

Figure 4 is an operating view, showing the manner in which the out form is ejected from the machine previous to tearing off the web to a form-length.

Figure 5 is a planview, showing all the parts in the position corresponding to that shown in Figure 1.

Figure 6 is a perspective, view of the adjustable'gage mounted on the fronttable, for positioning the web in line-space direction.

Figure 7 is a perspective view of the adjustable gage, which is mounted on the carriage for positioning'the out form, and shows a; clip for holding the form in inserted position.

Although this invention is illustratedas applied to an Underwood fan-fold typewriting machine of the type such as. disclosed in the patent to Wernery & Smith, No. 1,132,055, it will be understood that the invention could also be used to advantage in combination with any typewriting machine having a platen-elevatin mechanism.

In said fan-fold machine a platen 10 is loo,

revolubly mounted on platen-frame 11, which is pivotally mounted on a shaft- 12. The

platen is operatively connected to fingerwork in this invention, a fan-fold we pieces 13 by means of gears 14 and 15, which mesh with pinions 16, said gears 14 belng fast to a platen-axle 17.

Accordm to the method of handlin th;

isdrawn up from a suppl at the rear of the machine, and is inter caved with car-v leadin ed e is held down against a table 25 with the ot er hand 26.

The platen is held in its normal osition, as shown in Figure 1, by means of a latch 27, which engages a pin 28 on the frame 11, and in order that the laten ma be part1 elevated, as shown in igure 2, t e latch 2 is swung backwardly away from the pin 28. The platen is held in this position with one hand while a out form 29 is inserted between the feed-rolls and the platen and is laterall sitioned against a si e gage 30. The form is. then pulled over against a leading-edge gage 31, and is held in place by means of a finger 32, while the platen is again loweredto ,its normal position.

The leadin edge gage 31 is adjustably mounted on t e carriage, and, by means of this adjustment, it'is. ossible to so position the out form with re ation to the leading edge of the web, that when the platen is rotated rearwardly, to draw the out form and the web together, the leading edges of both. are matched. The laten is again rotated forwardly and the eadin edge of the web is inserted under a kni e 33, which serves as a means of cuttin off the web and also for guiding the leading edge thereof when the same is swung. down to the position shown in Figure 3, and the out form,

is ositioned for the first line of typing.

fter completely typing the first form by means of type-bars 34, the platen is rotated forwardly to feed the web a ainst a cuttingoifgag'e 35 and to eject tfie cut form,.as shown in Fi lifted, and the leading edge'of the web is 1 held against the gage 35 when the carbon carrier 20 is moved rearwardly by means of a handle 36, the platenbeing again lowered to its normal position, so as to hold the web while the first form is being torn off against the knife 33.

I In order to revent accidental shifting of the web when the platen is partially elevated to.- insert acut form thereunder, the gage 24 is provided with a side gage 37 forming an integral art thereof, the gage 24 being secured to t e table 25 by means of screws gure 4. The platen is then.

38, which are passed through slots 39, thus providing an adjustable gage for positioning the web in line-space direction.

The gage 31 is 'ad ustably mounted upon an adapter 40, whichv is secured to carriage 41 by means of screws 42 and serves as a means for positioning the gage in a plane tangential to the platen. The gage 31 forms an integralpart of a plate 43 against which the finger 32 bears to hold the out form thereon. Said plate 43 is provided with slots 44 to permit the line-spacing adjustment of the out form, and is secured to the adapter by means of screws 45.

In order to prevent the back-sliding of the web during the platen elevating operation,

,and in order to provide a loop under the platen, as shown in Figure 2, thus diminishing the effort required to hold the web against the gage 24, there ma be'provided springs 45 secured to the car on-carrier by means of screws 46, said s rings being designed. to bear upon rails 4 which serve as a guide for the carbon-carrier. Said springs provide a slight drag on the carbon-carrier, thereb preventing its accidental back movey ment ue to the weight of the web.

In the Underwood machine the knife 33 is fast to end plates 48 pivotally mounted on the platen-axle 17 and ma be swung, by means. of a finger-piece 49, rom its normal position shown in Figure 1 to the posiiece 49 isshown under the pressure of a nger 50.
